QUILOMBO, Carlos Diegues' historical saga, is a stirring fusion of folklore, political impact, and dynamic storytelling, realized in vibrant tropical colors and set to the pulsing beat of Gilberto Gil's rhythmic musical score.The story derives from fact: in 17th-century Brazil, groups of runaway enslaved Africans who escaped to mountainous jungle strongholds, where they formed self-governing communities known as quilombos.Like Alex Haley's ROOTS, this film chronicles Palmares, the most famous of these "Black Eldorados" which flourished for several decades under reign of the legendary chieftain Ganga Zumba.
